Unable to load Vi in teststand Error Code -18002

[Chakib11]

Hi,

I'm trying to debug a sequence in teststand, there is a step where I call a Labview VI when it running I got this error : 

"Error Code-18002 Unable to Load Labview VI ( ../path/...) . LabView already has the VI (../Path/..) "

Someone have an issue or explanation please?
